2,3,5,6-Tetrafluoroterephthalonitrile is a perfluoro aromatic dinitrile synthesis intermediate — a building block used in the manufacture of fluorinated specialty chemicals and pharmaceutical intermediates. Identity: CAS 1835-49-0.
What it is
2,3,5,6-Tetrafluoroterephthalonitrile (CAS 1835-49-0, C8F4N2) is a perfluoro aromatic dinitrile sold as a synthesis intermediate — a defined building block that downstream manufacturers convert into finished products.
Role in synthesis
The dinitrile and ring fluorines make it a building block for fluorinated specialties and pharma. The substitution pattern (isomer) is part of the identity — confirm the CAS to be sure the isomer matches your route, because position isomers react differently and lead to different products.
What it is used to make
It is a building block toward fluorinated specialty chemicals and pharmaceutical intermediates. RawSource supplies the intermediate; the downstream synthesis, product registration and any application or efficacy are the responsibility of the manufacturer that uses it.
Forms, grades and handling
Supplied to a defined assay with a Certificate of Analysis (CoA) per lot; define the assay and key impurity limits your route needs. Several halo-aromatic intermediates are hazardous and some are regulated — confirm regulatory status and handling for your jurisdiction, and always consult the current Safety Data Sheet (SDS). Typical values are not a guaranteed specification; the CoA governs.
Bulk and custom-quantity supply
RawSource sources 2,3,5,6-Tetrafluoroterephthalonitrile direct from producers in bulk and custom quantities, with CoA, TDS and SDS per lot. Tell us the assay and impurity limits and your sample/pilot/production quantity, and we will quote it and confirm supply continuity. See the full range in the intermediates guide.
